NR 228.06 NR 228.06 Application of effluent limitations and standards.

NR 228.06(1) (1) The effluent limitations and standards set forth in this chapter shall be used in accordance with this section to establish the quantity or quality of pollutants or pollutant properties which may be discharged by a point source subject to the provisions of this chapter, except as;

NR 228.06(1)(a) (a) They may be modified in accordance with subch. IV of ch. NR 220.

NR 228.06(1)(b) (b) They may be superseded by more stringent limitations and standards necessary to achieve water quality standards or meet other legal requirements, or

NR 228.06(1)(c) (c) They may be supplemented or superseded by standards or prohibitions for toxic pollutants or by additional limitations for other pollutants required to achieve water quality.

NR 228.06(2) (2) The production basis for application of the limitations and standards set forth in this chapter shall be the daily average of the maximum month production in the past year.

NR 228.06(3) (3) The limitations for pH and concentration limits for subcategory (3) in table 1 shall not apply to any untreated runoff from storage facilities designed, constructed, and operated to treat the volume of runoff which results from a 10 year, 24 hour rainfall event as set forth in s.
